Korniche is the lantern other lanterns get compared to. Its precision-engineered aluminium components clip together without silicone or cover caps, producing crisp lines inside and out and an installation time measured in minutes rather than hours.

We supply and install genuine Korniche roof lanterns across the UK, in the full size range and colour options, with the manufacturer guarantee backed by our own workmanship cover.
What sets Korniche apart is the engineering: a patented joint system that needs no on-roof cutting or sealing, fully thermally broken profiles with no cold bridging anywhere in the structure, and sightlines among the slimmest on the market. The result is a lantern that looks as clean from inside the kitchen as it does from the garden. Korniche lanterns are made to order to your exact dimensions, glazed with self-clean blue, clear or neutral solar-control units, and finished in grey, black, white or dual-colour. As approved installers we fit them nationwide; supply-only orders ship direct with full instructions.

The frame itself can be assembled on the kerb in under 30 minutes by a competent installer; a full fit including glazing and flashing is comfortably a one-day job. Manufacture lead time is typically one to two weeks.
Yes — the system is fully thermally broken with no metal-to-metal path from outside to inside, and paired with argon-filled units it achieves U-values that comfortably satisfy Building Regulations for extensions.
Every Korniche is made to order, so 'custom' is the standard. You give us the external kerb size and the lantern arrives fabricated to those exact dimensions.
